Latest Calibration of GLONASS P-Code Time Receivers

Abstract

The Russian GLONASS navigation system, although not yet finished, provides interesting opportunities for international time metrology. Its P-code signal shows an outstanding performance. In particular, it allows calibration of GLONASS time receivers with an uncertainty below 1 ns. Our paper reports the latest differential calibration of GLONASS P-code time receivers located at the AOS and the BIPM, by means of a portable receiver. Receiver time biases were determined for different GLONASS frequencies. Removing these biases, reaching sometimes 10 ns, allows time transfer with an accuracy of around 1 ns.
